    ABSTRACT: This study compared the coronal microleakage of three restorative materials used to seal the access cavity in root treated teeth. Thirty six teeth were prepared and three experimental groups were obturated and the access cavity filled with different materials; Group A--Intermediate Restorative Material, Group B--Fuji II and Group C--Dyract AP. Microleakage was assessed by Indian ink penetration. The mean coronal dye leakage for Group A was 0.895 mm, for Group B 1.914 mm and for Group C 3.245 mm. There was significantly (p < 0.05) more dye leakage in teeth restored with Dyract AP compared to those with Fuji II or IRM.

    ABSTRACT: Many of the new materials and techniques used in endodontics (root canal treatment) require considerable practice to master and many require continuing education courses to allow formal instruction. Nothing is known regarding techniques employed and views on continuing professional education (CPE) in endodotics by dentists in Trinidad and Tobago. With the shift toward evidence-based dentistry and rising patient expectation of quality oral health care, a survey was conducted to describe these issues. A self-administered postal questionnaire was sent to all registered dentists in Trinidad and Tobago. Seventy dentists responded after two mailings. Most respondents worked primarily in private practice (85.5 percent). Years since qualification ranged from 2 to 45 years and 54.3 percent were qualified for more than 10 years. Most frequent treatment of an acute dental abcess involved opening, preparing the canal(s), dressing and prescribing antibiotics (40 percent). Forty-one respondents (58.6 percent) ocassionally completed root canal treatment in a single visit. Isolation of the tooth for molar root treatment always caused difficulty for thirty-five respondents (50 percent) and rubber dam isolation was used routinely by only nine respondents (12.9 percent). Most respondents either filed (20 percent) or reamed (18 .6 percent) for canal preparation usually using K files. Thirty-three respondents (47 percent) used sodium hypochlorite to irrigate the tooth and thirty-one (44.3 percent) used cold lateral condensation of gutta percha to obturate. Thirty-four respondents (48.6 percent) subscribed to professional journals and sixty-seven (95.7 percent) had attended some form of Continuing Professional Education. Sixty-seven (95.7 percent) of respondents would attend CPE in endodontics if available in Trinidad and Tobago, with most (72.9 percent) preferring a lecture/seminar format addressing problem-solving and new techniques. Respondents to this survey showed use of a wide range of techniques and materials but still expressed considerable interest in developing their skills in endodontics through formal CPE..
